BRIDGEPORT -- The city school board decided Monday that its hearing on whether to fire Tisdale Principal Carmen Perez Dickson isn't over yet.

Testimony may have ended Oct. 4, but briefs from both sides were not received until Friday, and the board still hasn't gotten all of the evidence it requested.

The board voted to reopen the hearing in hopes of pushing back the 15-day time limit that statutes give the board to render a decision.

The board, which met Friday and then recessed the meeting to Monday, voted unanimously to recess again, until 5:30 p.m. Tuesday.

Board members want three years of discipline data from Tisdale School, dating back to the 2010-11 school year, including suspensions and office referrals, broken down by grade, age, gender and ethnicity.

The board also wants to know the total number of incidents and number of students involved.

The request came during the course of the hearing that began in June, after it was suggested Dickson was transferred to Tisdale to bring order to the school. As of Monday, the board still didn't have the data.

In a letter sent to City Attorney Mark Anastasi on Monday, Josephine Miller, an attorney for Dickson, said the evidentiary portion of the hearing can't be considered closed until the board -- and both parties -- have had a chance to review and respond to the data. At the very least, she said, the 15-day clock didn't start until the briefs were filed.

The board, however, wants both attorneys at its meeting Tuesday to agree on the record that a decision does not have to be reached by Saturday.

The board has yet to review the evidence, including three security videos that show Dickson dragging kindergarten children in the spring of 2012.

Dickson was suspended in July 2012, and Schools Superintendent Paul Vallas recommended that the veteran administrator be fired. Dickson opted to have the board, not an arbitration panel, hear the matter, a new experience for all of them.
